Why Is My Check Engine Light On?
Your vehicle’s check engine light (CEL) is part of the onboard diagnostics system (OBD-II), designed to alert you when something in your engine, emissions system, or drivetrain needs attention. Sometimes it’s a minor issue — like a loose gas cap — and other times it signals a problem that requires immediate repair.
Common Causes of a Check Engine Light:
- Faulty oxygen sensors
- Loose, cracked, or damaged gas cap
- Catalytic converter issues
- Spark plug or ignition coil failure
- Mass airflow sensor malfunction
- Emissions or EVAP system leaks
- Transmission-related fault codes
⚠️ Pro Tip: A blinking check engine light often means a serious misfire that could damage your engine — it’s best to stop driving and schedule diagnostics right away.
